To all whom it may cbm/1cm.'

Be it known that I, MAX BUCHMLLER, a citizen of the United States, residing in New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in .Candy- Making Machines, of which the following is a specification.

This invention is in the candy making art, and has for its object to provide improvements in the manufacture of lolly pops, to the forming and molding of the candy, and to the insertingv of the sticks into the formed or molded candy while this is held in position in a conveyer.

Mechanism embodying the present improvements will comprise candy forming or molding mechanism and a device for insert- '5 ing device.

ing the sticks into the molded candy together with various coperative and subsidiary devices.

Theseries of candy molds will preferably be mounted on a carrier in the form of an endless chain. In the machine illustrated herein each of the series of candy molds is divided between two adjacent links of the endless mold chain. The sticks are distributed by an endless chain, into lthe 'carrying seats of which chain they will drop from their receptacle. While the sticksv are carried by such seats they will be forced into the molded candy.

In the drawings accompanying land forming a part of this speciication Figure 1 is aside elevation of a practicable embodiment of a form of my invention. Fig.. 2 is a top 1 plan View of the machine as illustrated in Fig. 1. Fig. 3 is an end view of the machine looking from the left toward the right in Fig. 1, the feeding portion being removed in this View. Fig. 4 is an end view similar to Fig. 3 but showing the feeding portion. Fig. `5 is an enlarged plan view in detail illustrating the stick carrying chain, the candy carrying chain, and the stick actuat- Fig. 6c is a plan View of the cam plate for the stick actuator'. Fig. 7 is a perspective of a portion'of the `stick carrying chain. Fig, 8 is a perspective view molded candy therein.

Fig. t is an enlarged view of the candy carrylng and mold chain, illustrating the position of a retaining device for running over the candy carriers during the stick inserting operation. Fig. l0 is a top plan view of the portion of the mechanism illustrated in Fig. 9. Fig. 11 is a cross section of Fig. 10 taken on a plane at about the line lll- 11. Fig. 12 is a longitudinal section through two molds of the chain and is taken on av plane at about the line 12712 of Fig. 11. Fig. 13 is a side View of a portion of the stick carrying portion of the stick supplying mechanism. Fig. 14 is a top plan View of the devices illustrated in Fig. 13; and Fig. 15 is a perspective view of the delivery end of the stick hopper detached from the body o'f the hopper.

The form of machine herein illustrated embodies a candy conveyer having a series of continuously moving molds, into each of which molds in turn a sufficient quantity of the candy will be placed and molded into form. After the molding the end of a stick vill be caused to enter the cavity carrying the molded mass and be pressed into such The" cavities or molds, designated by 1, are each shown formed part upon one mold' memberQ and part on the adjacent mold member 2. The series of chain or mold members 2 are mounted on a carrier in the form of an endless sprocket chain 3 of considerable length. When the mold members are at the position between the sprocket wheels 4 and 5, which carry the mold chain, the halves of the mold are'closed together and a moldcavity is presented with an open top to which the candy will be fed by a feeding device, designated in a general way by 6. The feed illustrated embodies a set of two horizontal rolls 7--7 and an upright roll 8, all geared together to have the same surface speed. A guide 9 is employed for guiding the candy to the pass between the feed rolls. The rolled candy is delivered from the pass of the feed rolls etl over the table 10 and onto the mold memin their path of travel present a plain unbroken surface with the exception of the die cavities. The candy fed onto the mold members is pressed into the mold cavities and off the top surfaces of the mold members, there A gearing with the driving shaft, there being illustrated. in the train gear wheels 17, 18, 19 and 20, the latter of which is fast upon the driving shaft. The feed rolls are also connected by a suitable train of gearing with this latter gear wheel. The shaft 21 of the sprocket wheel 5 is mounted in an adjustable bearing member 22 and is controlled by means of a set screw 23 for the purpose of adjusting tension or lslack in the sprocket chain 3.

The pressing or molding roller 11 is located above thechain 3 not far from the sprocket wheel 4. Over the chain near the sprocket wheel 5 is mounted an auxiliary or finishing pressing roller 24. This roller 24 is provided with an interrupted working face and presents a number of smoothing members 25. The auxiliary presser roll is driven by means of gear wheels 26, 27, 28

and 29 from the shaft 21 of thesprocket wheel 5, the gearing being so timed that the surface speed of these members 25 will be equal to the surface speed ofthe mold members.

After the candy has been molded, the sticks 30 will be 'inserted in the candy. A stick carrying device is illustrated, in the form ofan endless chain 31. The chain runs .over the sprocket wheels 32 and 33 which are suitably mounted in standards of the machine frame. The sprocket wheel 32 has fast with it a gear wheel 34, which, by means of a train ofr gears 35-36, will be driven from the drivmg shaft 12. Each of the -linksof the stick chain 31 is provided with a stick seat 37 of substantially the length of the width of the link and of such dimen-` sions thatl it will conveniently accommodate a stick. The upper run of this stick chain -is shown placed adjacent to the path of movement of the candy Vcarriers between the pressing or molding roller 11 and the finishing roller 24. The gearing is such that the sticks and the candy will have coincidence of speed as well as coincidence of direction.

Each link of the stick chain is provided with a stick pusher, a form of which is illustrated in perspective in Fig. 8 and comprises a slide member 38 which is received by suitable guideways in a link and is provided with a stick engaging member 39 adapted to traverse the stick seat. The traverse of the stick pusher is effected by means of an engaging member 40 carried by the slide 38.

The engaging member for each pusher will,

.when the link carrying the same approaches. the stick inserting zone, 'run into the cam slot 41 of a cam plate 42 and force the end of the stick in the stick seat into the cavity of the candy carrier and into the molded candy therein.

The stick inserting mechanism is located.

at such a position relative to the molding devices that the operation of inserting the sticks into the candy will vnot interfere with the molding operation. Before each link of the stick chain reaches the active portion of the 4cam groove 41 it will be provided with a stick. A supply of the sticks is shown in a hopper 43 which is located zibove/ the path of movement vof the upper run of the stick chain, just in advance of the stick inserting zone. The lower portion of the hopper is provided with a movable mouth or delivery end 44 which is ivoted at 45 i to the main hopper and has 1 s opening located in position just above the upper surface' of the chain, so that the sticks in this `delivery portion of the hopper will rest upon the chain as it moves under the hopper. For preventing the sticks/` becoming clogged in the hopper the delivery portion; will 4be given a reciprocatory or vibratory motion parallel with the stick chain movement. For' this purpose an eccentric 46 is mounted u on a shaft 47 havin a bearing in a standar 48. The shaft 47 is rotated by means of a 'train of gearing 49 and 50, which latter gear wheel meshes with the gear wheel 34. In some instances it may be;A

desirable to move the lower portion of the hopper forward in coincidence with the' lchain for a short distance and then rapidly draw it backward in a counter direction to the travel of the chain. Sometimes it may happen that a broken or bent stick or one which is carrying some foreign substance may not be properly seated in the stick seat in the chain. To prevent breakage and damage to the machinery, by :such misplaced stick, the front portion 51 of the movable part 'of the hopper may be pivoted, as at 52, and

be provided with extension springs, 53.v

This portion 51 will Lthen, when suiiicient internal pressure is applied, move forward in the direction of chain movement, and permit the misplaced stick to move outl of the hopper. After which the rings will draw the pivoted plate ,51 back into its original! of the position andthe normal operation machine will continue.V

During the insertion of the sticks into the assuring the escape of arianna moldcd candy it may be desirable to cover the cavities containing the candy withl a- 54 and to vhold this in a raised position..l To permit such raising and also to hold the plate to its Work it is provided with a pair of arms 56 to each of which is pivotedla pin 57, which pin enters a rotatable guide member 58 mounted vupon a standard 59. Between the guide member 58 andthe arm 56 there is a compression spring 60. The construction is such that the pressure of the spring will be exerted to hold the retaining plate member down. When it is desired to raise the plate the handle 61 can be taken hold of, the plate swung on its pivot, which Will bring the varm 56 down and in the position opposite to that occupied in Fig. 11 and the force of the spring 60 Will then be exerted to hold plate 54 in a raised position.

To give the finished lolly pop the :form demanded by the trade the sides of the mold cavity are caused to overhang,l as at 62. This overhang WouldI normally interfere with the removing of the lolly pop from/the mold unless the mold were separable. The mold is illustrated herein as separable, and its two halves 63 and 64, see Fig. 12, each `carried by a separate link, Will :as the lsprocket chains 3 pass around' the sprocket wheel 5 be moved apart, (see Fig.y 1,) so that the molds are opened, upon the further movement of the chain the lolly pops Will be discharged. The blocks which carry the pockets or mold spaces forthe pieces of candy are mounted upon extensions 71 so thatas the chain 3 passes over the sprocket Wheel 5 the portion of the block uWhich contains the mold Will be at a greater radial distance from the center about which the chain is then curving than are the body portions of the links carrying such mold block, and this will not only cause an opening of the mold but will cause one-half to move away from the other half of the mold, thus the molded candy. The candy could not escape With the mold shut owing to the undercutting of the mold above referred to. The lolly pops may drop from the molds upon an endless apron 65.a

mounted upon suitable rollers 66-67, one of Which is driven by means of a gear Wheel 68 which meshes with idler 69, which in turn meshes with gear 29 which is mounted upon shaft 21. The endless apron will carry the finished article to some point for disltribution, `as for instance to a box 70.

. With aseries of blocks,

At the Working zone lof the presser rolls 65 and the stick inserting mechanism the candy carrier will run over a support in the nature cfa-table' 72, and at the Working zone ofthe stick insertin mechanism an vabutment 7 3 Will be provi ed for resisting the thrust of the insertion of the sticks into the candy.

In Fig. llthe pivot or rivet member 74 for the links of the chain 3 are illustrated,

.these being in sucha'position that the sprocket Wheels 4 and 5 Will engage between 75 side members of the chain. In Fig. 12 the molds are shown in closed position, that is a cavity 63 is shown in one end of one block and a complemental cavity 64 in the adjacent end of the next block. When the blocks are held in such a posi- Y tion. that the complemental mold cavities .c are together they Will form a mold, when the adjacent bloc-ks are moved in such positionone relative to the other that the die cavities move away one from the other the molds will open, as is seen at the right hand v end of Fig. 1, at Which position the candy Will be discharged. 4
